Synthesis Weaver

A Synthesis Weaver uses a special device that combines two different sources of power to conjure a powerful aegis greater than the sum of its parts.

Expanded spell list

When you reach an Artificer level specified in the Synthesis Weaver Spells table, you thereafter always have the listed spells prepared.

3: Bane, Protection from evil and good

5: Mirror image, Prayer of healing

9: magic circle, remove curse

13: fire shield, locate creature

17: dispel evil and good, hold monster

Sythesis furnace

When you finish a Long Rest while holding Tinker’s Tools, you can create a device called a Synthesis Furnace. This can be a belt, helmet, ring, gauntlet, or any other similar wearable item (your choice). It can’t be removed against your will, and only you can use its properties while you are wearing it. If you create another Synthesis Furnace, the previous one is immediately destroyed.

Synthesised aegis

You can conjure a protective aegis by fusing two contrasting forces using your Synthesis Furnace.

Synthesis Compounds. You know 2 Artificial Compounds and 2 Vital Compounds, each of which is detailed under the “Synthesis Compounds” section at the end of this subclass’s description.

Learning New Compounds. You learn two new compounds of any type (Artificial or Vital) when you reach higher Artificer levels: at level 5 (6 compounds), level 9 (8 compounds), level 13 (10 compounds), and level 17 (12 compounds). Each time you gain an Artificer level, you can replace one compound you know with a different one of the same type.

Synthesized Aegis. When you roll Initiative (provided you are not surprised), or as a Bonus Action during your turn, and choose one Artificial and one Vital Compound that you know. You must be wearing your Synthesis Furnace in order to do so. When you do so, you conjure a Synthesis Aegis that enshrouds you for 1 hour, after which the aegis vanishes. The aegis vanishes early if you are reduced to 0 Hit Points, or as an action during your turn. You determine its appearance, such as a suit of armor themed around the compounds, and whether or not the aegis conceals your face. You can conjure the aegis once, and you can’t do so again until you finish a Short or Long Rest, or expend a level 1+ spell slot as part of conjuring the aegis.

Aegis Armor. While you aren’t wearing any armor or wielding a Shield, your base Armor Class equals 13 plus your Intelligence modifier. If you are wearing armor, you can choose to have the aegis replace it. Compound Effects. You gain the effects of the Artificial and Vital Compounds used to conjure the aegis.

Compound Switch. As a Bonus Action during your turn, you can change your aegis’ Artificial or Vital Compound (or both) and replace it with another one you know of the same type. When you do so, the compounds of the aegis change, losing the properties of the previous compounds and gaining the properties of the new ones.

Weapon Conjure. As part of conjuring the aegis, or as part of using Compound Switch, you can conjure a Synthesis Weapon. Synthesis Pair. Certain combinations of Artificial and Vital Compounds form a Synthesis Pair. If your aegis’ compounds are on the same row on the Synthesis Pair table, you gain the following additional benefits: the damage of your Unarmed Strikes increases to a d6, your Speed increases by 10 feet, and your AC increases by 1.

Synthesis Pair

• Artisan Warrior
• Implement Locomotion
• Folklore Flora
• Treasure Marvel
• Cryptid Mythical
• War Machine Beast

Compound Maelstrom. As a Bonus Action, you accumulate compound energy into your Synthesis Furnace. You can also do so as part of using Compound Switch (no additional action required). The next time you deal damage with an attack or spell, you deal an additional 2d8 Force damage. The additional Force damage increases when you reach higher Artificer levels: at level 5 (3d8), level 9 (4d8), level 13 (5d8), and level 17 (6d8). You can use this property once, and you can’t do so again until the next time you conjure your aegis or if you expend a level 1+ spell slot as part of the same Bonus Action.
